Yeah, I get it now. The only thing is, it's frozen and won't move. I should have removed the coralline from it but I never realized that it had a moving part. Lol, I guess the best I can hope for is that it works itself out. I think it might help when I get the other pump in... My pump outlet on the Eheim and the pipe size of the outlet nozzle are different sizes. I'm going to Lowes to see if I can get a straight reducing connector today.
In the meantime, I tuned the light on to check the gate and there are still microbubbles, but much less. I bet it will slow to nothing. Hopefully, you're right and it just needs to be broken in.
